False-to avoid mushroom poisoning, you should follow these five rules: 1. identify each and every mushroom you collect, and only eat those whose identification you are sure of. when in doubt, throw it out. 2. strictly avoid: any mushroom that looks like an amanita (parasol-shaped mushrooms with white gills); all little brown mushrooms; all false morels. 3. some people are allergic to even the safest mushrooms. the first time you try a new wild mushroom, it is important that you eat only a small amount and wait 24 hours before eating more. 4. as with other foods, rotting mushrooms can make you ill. eat only firm, fresh, undecayed mushrooms. 5. most wild mushrooms should not be eaten raw or in large quantities, since they are difficult to digest.
